iv MADI 700 Series Guide
Chapter 1: Introduction to the MADI 700 Series This guide describes the following MADI 700-series converters for System5: • AM713 Analog to MADI Converter • MA703 MADI to Analog Converter • DM714 Digital to MADI Converter • MD704 MADI to Digital Converter AM713/MA703 The AM713 and MA703 converters provide MADI conversion to/from analog equipment such as consoles, tape decks, microphone preamplifiers and other analog devices.
Power On Sequence We recommend powering up the converters only after verifying the presence of a valid sync signal. After powering up the converters, the meter LEDs flash briefly and the Sample Rate and Sample Rate Source LEDs blink as the converter senses the incoming Sample Rate source and Sample Rate. We recommend monitoring the power-up sequence to verify the converters have correctly auto-sensed the desired Sample Rate Source and Sample Rate.

Chapter 2: AM713 and MA703 Converters Features Applications Professional grade audio conversion is accomplished utilizing 128 times over-sampled noise-shaped delta-sigma techniques. The analog to digital conversion employs a multi-bit modular architecture while the digital to analog conversion employs a single-bit modulator architecture. Low-jitter reference clocks are provided utilizing digital PLL techniques with VCXO and VCO oscillators.
AM713/MA703 Front Panel This section discusses both front panels and notes their few differences. AM713 Front Panel Signal Strength LEDs Each of the 28 channels has a four-segment LED that represents the following signal levels: -42 dB, -18 dB, -6 dB (green), -0.05 dB (red). Trim Pots Access Three trim pots adjust the maximum analog input level of channels 1–8, 9–16, and 17–24 in 2-dB steps between +12 and +26 dBu. SR Conv This indicates sample-rate conversion activity on the auxiliary digital inputs.
AM713 Back Panel AM713 Back Panel Input Voltage Selector This red switch allows the unit to operate in either 110/115 VAC or 220/230/240 VAC environments. A fuse must also be changed for 220/230/240 VAC operation. Units are shipped set and fused for 110/115 VAC. S/PDIF Digital Input (RCA) Stereo S/PDIF digital input on one RCA connector. Functions in parallel with the auxiliary AES/EBU input and the two inputs should not be used simultaneously.
MA703 Back Panel MA703 Back Panel Input Voltage Selector This red switch sets the unit to either 110/115 VAC or 220/230/240 VAC environments. A fuse must also be changed for 220/230/240 VAC operation. Units are shipped set and fused for 110/115 VAC. S/PDIF Digital Outputs (RCA) Stereo S/PDIF digital output on one RCA connector. Functions in parallel with the auxiliary AES/EBU output and the two inputs should not be used simultaneously.
Synchronization AM713 MA703 The AM713 Sample Rate is set externally by one of two source signals or internally by crystals and associated circuitry. The Sample Rate Source is determined automatically by the presence of signals when the AM713 is powered on. The order in which external signals are tested for presence is: AES, Word, Internal.

Chapter 3: DM714 and MD704 Converters Features Applications AES/EBU and Word Clock external sync inputs on both units provide synchronization to digital systems. Sample Rate Source and Sample Rate are automatically sensed by both units. Supported sample rates include 44.1, 48, 88.2, and 96 kHz. In addition, pull-up and pull-down rates for the standard sample rates, as well as custom sample rates are available.
